Luz is now off of Rytary for the time being after about 6 weeks of use. She started having Freezing of Gait which intensified with the last 2 weeks of use.
Within a day and a half off Rytary and back to Sinemet IR the freezing of gait subsided and only occasionally appears when she is overtired. She had a similar result with Sinemet CR so it looks like Rytary and Sinemet CR accumulate across doses for her.
